Executive brief
A memory handling vulnerability exists in Apple's operating systems, including iOS, macOS, and watchOS. An attacker in close physical proximity to a device could potentially corrupt its memory, which may lead to system instability or unauthorized code execution. Users should update to version 26.6 or later to resolve this issue.
Technical details
A memory corruption vulnerability exists across multiple Apple operating systems due to insufficient memory handling. The vulnerability requires an attacker to be in physical proximity to the target device to exploit the flaw. Successful exploitation could allow an attacker to corrupt process memory, potentially leading to arbitrary code execution or a denial-of-service condition. Apple addressed the issue by improving memory management logic. The fix is available in iOS 26.6, iPadOS 26.6, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, and watchOS 26.6.
